Abstract
Exposure of rabbit bucks to environmental stress such as cold or heat stress, wind, ventilation, light and solar radiation negatively affects the fertility, growth and reproductive traits by inducing the oxidative stress (Alejandro et al., 2014). These stress induce an increase in production of reactive oxygen species (ROS), which determines semen characteristics and sperm-oocyte fusion (Akiyama, 1999). Low levels of ROS has an important role in the normal function of a reproductive system and in the pathogenesis of infertility, also play a role in other reproductive organ diseases (El-Tohamy and El-Nattat, 2010). While, high levels of ROS formation can lead to apoptosis and DNA strand breaks of spermatogenic cells (Paul et al., 2009).
